Proto J5209MH 9mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5209MH is a 9 mm, 6-point hand socket designed for use with a 3/8 inch drive ratchet or breaker bar. Constructed from alloy steel with a chrome-plated finish, this standard-length socket delivers reliable torque transfer and corrosion resistance in daily shop and field use. The 6-point geometry maximizes contact with fastener flats, reducing rounding on worn or rusted hardware. It meets AS4984A and ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional hand tool applications. The socket is not tether capable and is sold individually.

The J5209MH suits general mechanical maintenance, automotive service, and industrial assembly tasks where a 9 mm fastener and a 3/8 inch drive setup are required. It is appropriate for use in automotive shops, fleet maintenance facilities, and light industrial environments. Licensed mechanics, maintenance technicians, and experienced tradespeople working on engines, suspension components, or equipment panels will find this a standard-duty option for routine fastener work.

Installation Notes

This socket is installed and removed by hand tool technicians using standard 3/8 inch drive ratchets or torque wrenches. Always ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket and drive square for wear or cracks before each use, and remove from service if deformation is observed. This product is not rated for impact driver use.
